When it comes to the car antenna, I believe many friends are not unfamiliar, because there are too many private cars now, and we have a lot of opportunities to get in touch with vehicles. It's up to us to hear, and there may not be many friends who really know. Next, let's talk about the characteristics of the car antenna and relevant precautions.

1、 Characteristics of vehicle antenna

1. Features related to vehicle construction:

The length of the single axis antenna should reach a quarter of the wavelength of the received radio wave, but the wireless length that can be installed on the vehicle is about 1m.

2. Characteristics related to use environment:

Considering the demand of arbitrarily moving cars, the on-board antenna is generally a non pointing antenna. Now the improvement of radio and TV receiver is being promoted. The performance that the on-board antenna must meet includes water resistance, shock resistance, corrosion resistance, etc. at the same time, its safety and impact on the shape of the whole vehicle should be considered.

3. Multimedia related features:

Ensure that the on-board antenna is not interfered by other antennas, ensure its relevant acceptance performance, ensure the feasibility of setting and merchantability in appearance, etc. multiple antennas can be installed at a limited position.

2、 Relevant precautions

1. Note that the vehicle body shall be grounded;

2. Noise shall be considered;

3. Relevant waterproof and drainage shall be considered;

4. Pay attention to wind resistance noise.

　　vehicle mounted antennaIt can be said that it is necessary for driving now. On the one hand, understanding the relevant knowledge of vehicle antenna can increase their own knowledge reserve. On the other hand, it is more critical to facilitate their better use of vehicle antenna. According to the characteristics of vehicle antenna and relevant precautions, we will introduce it here. I hope the content of this article will be of positive help to you.
